Title: Process for the preparation of aromatic bis(ether anhydrides)
Inventor: WEBB JIMMY LYNN
IPC: C07C51/567
Filed: 1982-04-08
Abstract: A process for the preparation of aromatic bis(ether phthalic anhydride), for example 2,2-bis[4-(3,4-dicarboxyphenoxy)phenyl]propane dianhydride, by exchange reaction between molten aromatic bis(ether imide) and phthalic anhydride in the presence of water and an imide-anhydride exchange catalyst is made available. It has been found that a production rate increase for aromatic bis(ether phthalic anhydride) occurs if the molten aromatic bis(ether imide) is brought together with the phthalic anhydride in the form of an aqueous feed mixture of phthalic acid and exchange catalyst and the resulting mixture brought into equilibrium is extracted with organic solvent.
Patent DE-3213654-A1 (DE)
Title: Central shutter for cameras, in particular technical cameras
Inventor: BAAB ALBERT
IPC: G03B9/06
Filed: 1982-04-14
Abstract: In the assembly of central shutters whose aperture mechanism is equipped for the purpose of being matched to the brightness of the lens with a detachable and settable adjusting slide mounted on the aperture positioner, carrying out the setting operation has proved to be difficult to the extent that it is no longer possible to undertake the relative displacement of the adjusting slide with respect to the aperture positioner with the required delicacy. The cause of the difficulty is that the aperture positioner, which is designed as a flat ring, is difficult to grasp and, moreover, the ability of the two parts, which lie fully on top of one another, to slide has also been perceived as defective. In order to facilitate the setting of the aperture positioner relative to the adjusting slide and thus at the same time to configure this operation more rationally, it has been proposed to make use for the purpose of moving the aperture positioner of an auxiliary means of the type of a socket spanner or the like, which is provided with projections and when being attached to the shutter can be engaged both with a fixed rotary bearing found on the shutter baseplate, and with the aperture positioner.
Patent DE-3216930-A1 (DE)
Title: Process for recovering silver
Inventor: CORNELIUS GUENTHER
IPC: C22B11/02
Filed: 1982-05-06
Abstract: In the recovery of silver from silver concentrates by means of a cupellation process in a converter by blowing oxygen onto the molten silver-containing base metal alloys, the energy balance is unsatisfactory and, moreover, too much pure oxygen is consumed during the cupellation work. These disadvantages are avoided if the melting of the silver-containing base metal alloys is not carried out using conventional gas/air burners but using burners which are operated with a gas/pure oxygen mixture.
Patent DE-3218448-A1 (DE)
Title: Circuit arrangement with a switched-mode controller which can be stopped when critical disturbance values are exceeded
Inventor: HORSTKOTTE RAINER ING GRAD
IPC: H02M1/36
Filed: 1982-05-15
Abstract: This circuit arrangement contains a monitoring element (10, 11) which is supplied with a disturbance value. The output (12) of the monitoring element (10, 11) is connected either to the input or to the output (6) of a control amplifier (2) which has a feedback network (3) which causes a dead time in a control loop which includes a pulse duration modulator (1), fed by the control amplifier (2), and switching transistors of the switched-mode controller which generates a uniform output voltage or a uniform output current. When the switched-mode controller is stopped, the monitoring element (10, 11) sets the input or the output of the control amplifier (2) to a control error of zero or approximately zero in the case of a disturbance which is below a critical threshold. After the critical threshold has been exceeded, the switched-mode controller begins to operate with minimum duty ratio due to the presetting by the control amplifier. This prevents the output voltage from having transient amplitudes which are too high. <IMAGE>

Patent DE-3311385-A1 (DE)
Title: Method for operating terminals of a digital subscriber connection
Inventor: KRAUTKRAEMER WILLFRIED DIPL IN
IPC: H04M19/08
Filed: 1983-03-29
Abstract: A subscriber interface at the subscriber end of a digital subscriber connection is powered from the exchange via the subscriber connection line, where the power supply is sufficient to supply only a small number of terminals which can be connected via a data line to the subscriber interface. If a plurality of terminals are intended to be connected to the data line, the subscriber interface is to be equipped with an additional power supply device for this purpose. If this power supply device fails, the feed voltage on the data line is reduced for a specific period by the subscriber interface to a first voltage value which differs from the normal feed voltage, whereupon any terminals connected to the data line are disconnected from it. The feed voltage is subsequently increased once more to the normal value. As soon as a terminal accesses the data line, the feed voltage is reduced by the subscriber interface to a second voltage value which differs from the normal feed voltage. This is the criterion which prevents the connection of further terminals to the data line. The individual voltage values are selected in such a way that the second voltage value lies between the first voltage value and the normal feed voltage.

Patent DE-3324857-A1 (DE)
Title: Apparatus for carrying out a thermal product treatment in a fluidised bed, especially a fluidised bed furnace
Inventor: PAWLITSCHEK ERHARD DIPL ING
IPC: F23G5/30
Filed: 1983-07-09
Abstract: The apparatus, especially intended for the combustion of refuse which is mixed with added incombustible solids, is equipped, instead of with the inflow tray which is usual per se for such systems, with a feed system for flow medium, the outlet openings of which open within the bed material at a predetermined spacing under the surface of the bed material filling with the formation of free interspaces between adjacent outlet openings. Accordingly, incombustible solids, such as stones, which are present in the fluidised bed formed over the openings of the flow medium outlet openings due to flow medium being blown in, can enter between these outlet openings into the non-fluidised bed material and during continuous operation of the apparatus are drawn off together with bed material through a bottom discharge opening and screened out from the bed material before this is returned to the process.

Patent DE-3336213-A1 (DE)
Title: Plug connector for electrical leads
Inventor: SIFFEL ROLAND DIPL ING
IPC: H01R13/64
Filed: 1983-10-05
Abstract: In a plug connector for electrical leads, having a male strip connector, which is connected thereto, and a female strip connector, which is held in a retaining part, and having means (17) for the mechanically-coded connection of these strips, a web (15) for positively-locking engagement into a mating piece of the female connector strip is arranged in the retaining part (16) for the mechanically-coded orientation of the female connector strip (11) in its retaining part (16), which mating piece is a socket chamber (14) which is fitted with contact pieces. This socket chamber may be open at the sides, thus forming a groove. There is therefore no need to construct special different shapes for positively-locking engagement on the female connector strip. A tool which forms the female connector strips as individual items is thus simplified. When the female connector strips are cut off from the female connector strip rod, the separating cut may be placed such that the chamber (14) which is open at the side is produced (Fig. 2). <IMAGE>
